The purpose of this study is to determine the possibility of using Flos Sophora japonica as natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of Flos Sophora japonica a were measured. The contents of carbohydrate, crude protein, crude lipid and ash are 67.76%, 19.87%, 4.61% and 7.76%. And the calories of Flos Sophora japonica Linne was 318.32 Kcal. Total dietary fiber was 25.35% of total carbohydrates. The percentages of water soluble dietary fiber to insoluble dietary fiber were 1.80 % and 23.56 %, respectively. The protein were contained total 18 different kinds of amino acids. The contents of non-essential and essential amino acids were 4,898.78mg and 5,953.51mg. The K was the largest mineral followed by Ca, P and Mg, which means Flos Sophora japonica Linne is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 29.69%, 34.93% and 35.38%. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The content of vitamin C in Flos Sophora japonica Linne was higher than that of any other plant, which suggest that it could increase blood elasticity. The content of rutin, which is responsible for capillary vessel permeability, was 22.60%. The contents of water soluble antioxidative materials in 1 mL of water-extracted Flos Sophora japonica Linne were 3.9 ${\mu}$g which is comparable to 1233.0 mmol of vitamin C in antioxidant effect. The general nutrients and other antioxidatant bioactive materials in Flos Sophora japonica Linne were also potential materials for good health food. It is expected that follow up study of Flos Sophora japonica Linne through developing processed food and evaluation of their functional properties would provide useful information as a source of medicinal foods.

Purpose: This study aimed to investigate the clinical and metabolic determinants of circulating soluble leptin receptor (CSLR) and free leptin index (FLI) in pre-pubertal obese male children. Methods: We conducted a preliminary cross-sectional study at three tertiary hospitals and one public primary school. Eighty obese male children without growth and developmental abnormalities aged 5-9 years were recruited. In these children, obesity was solely caused by excessive food intake, and not by acute illness, medications, endocrine abnormalities, or any syndrome. Body mass index (BMI), body fat mass, carbohydrate intake, fat intake, high density lipoprotein cholesterol level, low density lipoprotein cholesterol level, triglyceride level, and Homeostatic Model Assessment for Insulin Resistance are the potential determinants for leptin regulation, which is represented by CSLR level and FLI. Results: Carbohydrate was the main source of energy. BMI and body fat mass had negative weak correlation with CSLR and positive weak correlation with FLI. Furthermore, carbohydrate intake was found to be independently associated with CSLR based on the results of the multiple linear regression analysis. Following an increase in carbohydrate intake, CSLR level decreased progressively without any negative peak. Conclusion: Leptin regulation in prepubertal obese male children is associated with body composition and dietary intake. Carbohydrate intake is useful for predicting CSLR. Lipid profiles and insulin resistance are not related to both CSLR and FLI. Treatment and prevention of leptin resistance in obese children should focus on reducing BMI, fat mass, and carbohydrate intake.

High consumption of fruits and vegetables has been suggested to provide some protection to smokers who are exposed to an increased risk of numerous cancers and other degenerative diseases. Carrot is the most important source of dietary ${\beta}$-carotene. Therefore, the objective of this study was to investigate whether carrot juice supplementation to smokers can protect against lymphocyte DNA damage and to compare the effect of supplementationof capsules containing purified ${\beta}$-carotene or a placebo (simple lactose). The study was conducted in a randomized and placebo-controlled design. After a depletion period of 14 days, 48 smokers were supplemented with either carrot juice (n = 18), purified ${\beta}$-carotene (n = 16) or placebo (n = 14). Each group was supplemented for 8 weeks with approximately 20.49 mg of ${\beta}$-carotene/day and 1.2 mg of vitamin C/day, as carrot juice (300 ml/day) or purified ${\beta}$-carotene (20.49 mg of ${\beta}$-carotene, 1 capsule/day). Lymphocyte DNA damage was determined using the COMET assay under alkaline conditions and damage was quantified by measuring tail moment (TM), tail length (TL), and% DNA in the tail. Lymphocyte DNA damage was significantly decreased in the carrot juice group in all three measurements. The group that received purified ${\beta}$-carotene also showed a significant decrease in lymphocyte DNA damage in all three measurements. However, no significant changes in DNA damage was observed for the placebo group except TM (P = 0.016). Erythrocyte antioxidant enzyme was not significantly changed after supplementation. Similarly plasma lipid profiles were not different after carrot juice, ${\beta}$-carotene and placebo supplementation. These results suggest that while the placebo group failed to show any protective effect, carrot juice containing beta-carotene or purified ${\beta}$-carotene itself had great antioxidative potential in preventing damage to lymphocyte DNA in smokers.

The present study aimed to assess the effect of dietary substitution of soybean meal (SBM) with dehulled-micronized faba bean (Vicia faba var. minor) in guinea fowl broilers on their growth traits, carcass quality, and meat fatty acids composition. In this trial, 120 day-old guinea fowl keets were randomly assigned to two treatments which were fed from hatch to 12 weeks of age. Birds were fed two wheat middlings-based diets comprising of a control treatment which contained SBM (78.3 g/kg) and a test diet containing dehulled-micronized faba bean (130 g/kg) as the main protein source. Substituting SBM with faba bean had no adverse effect on growth traits, dressing percentage, or breast and thigh muscles relative weight of the guinea fowls. Conversely, a decrease (p<0.05) of abdominal fat was found in guinea fowls fed the faba bean-diet. Breast muscle of birds fed faba bean had higher $L^*$ score (p<0.05) and water-holding capacity (p<0.05) than the SBM control diet. Meat from guinea fowls fed faba bean had less total lipids (p<0.05) and cholesterol (p<0.01), and higher concentrations of phospholipids (p<0.01). Feeding faba bean increased polyunsaturated fatty acid concentrations in breast meat and decreased the saturated fatty acid levels. Moreover, dietary faba bean improved the atherogenic and thrombogenic indexes in guinea fowl breast meat. Results indicated that substitution of SBM with faba bean meal in guinea fowl diet can improve carcass qualitative traits, enhancing also meat lipid profile without negatively affecting growth performance.

The aim of the present study was to investigate the effect of duck extract on lipids. Rats in the experimental group were orally administered with duck extract for four weeks. The half of the supplementation was composed of duck meat and the other of the supplementation was composed of oriental herbs. Weight gain, diet intake, and food efficiency ratio were compared between control and experimental groups. Organ weight, lengths of small/large intestines, and the following plasma biochemical parameters were also measured: hemoglobin, hemoglobin, GOT, GPT, blood glucose concentration, lipids of plasma, liver, feces. Spleen index (weight/100 g body weight) of the rats in the experimental group was significantly higher than those in the control group due to increase in fat intake from the supplementation of duck meat. The large intestines of the rats in the experimental group was significantly larger due to the supplementation with dietary fiber derived from herbs in the extract. There were significant higher levels of plasma hematocrit, GOT, total cholesterol, and HDL-cholesterol in the rats of the experimental group. From the results, although duck meat is a source of animal food, the fat profile of duck extract, such as the ratio of polyunsaturated fatty acids to saturated fatty acids appears to be beneficial to human health. These findings suggest a possible anti-hyperlipidemic effect of duck extract. (Korean J Nutrition 36(1): 3∼8, 2003)
